Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Method provided by the invention is sequentially carried out expanding treatment, ultra-fine grinding and ultra high pressure treatment to material, active ingredient in root of kudzu vine cell is fully extracted as kudzu root flavone etc., simultaneously also completely retain the composition that dietary fiber and cellulose etc. in the root of kudzu vine are of value to human body, make starch gelatinization, the biological utilisation that improves kudzu-vine root powder is worth.
Method provided by the invention comprises that root of kudzu vine raw material is carried out to expanding treatment, the first ultra-fine grinding and ultra high pressure treatment obtains kudzu-vine root powder.Expanding treatment herein refers to root of kudzu vine raw material pressurized, heated in closed container, and decompression suddenly afterwards makes the moisture gasification in root of kudzu vine raw material, the inner processing means that form a large amount of apertures of root of kudzu vine raw material expansion pueraria starch.The means that can realize this effect in this area all can be in the present invention.
Expanding treatment condition is 80～105 DEG C of swelling temperatures, charging water content 2～5%.Carry out with this understanding expanding treatment and can well control the gelatinization degree of starch in raw pueraria powder, only make starch molecule occur slightly expanded, improve the loosening degree of starch molecule crystal structure, avoid excessive gelatinization after starch Hole quantity reduce.More preferably 80～95 DEG C of swelling temperatures, carry out expanding treatment effect optimum by this temperature.Under this condition, gelatinization can also allow the cellulose concurrent first portion fracture that fully stretches, and is conducive to cellulose fully fracture in follow-up superfine technique.Technological parameter cannot not obtain above-mentioned effect within the scope of this.Once and occur that excessive gelatinization also can reduce the effect that reconstitutes of gained kudzu-vine root powder, this kudzu-vine root powder is easily lumpd in the time reconstituting, mouthfeel is too sticked together without salubrious sense.
Preferably expanding treatment is that Screw Extrusion is expanded.Moisture in the root of kudzu vine, under the dual transformation of this pressure and temperature, promptly steams from root of kudzu vine material, makes the countless micropores of Starch formation in root of kudzu vine cell.Cell liquid in root of kudzu vine cell comprises the benefit materials such as a large amount of each amino acids and kudzu root flavone, and cell liquid enters in the hole of starch under the effect of capillary syring, makes finished product reconstitute rear all kinds of benefit materials and is easy to separate out.
Expandedly can also make starch gelatinization, the starch molecule volume after gelatinization reduces to form the carbohydrate of absorption easy to digest.After expanding treatment, account for the dietary fiber of root of kudzu vine cell gross mass 30%, molecular structure changes, and changes digestible Polydextrose into and improves cellulosic utilization rate in gained kudzu-vine root powder.In root of kudzu vine raw material, also contain 9.89*10
-2the protein of g/g, the sex change after expanding treatment of these protein is degraded into the little molecule amino acid that is easy to digest and assimilate, and has improved the utilization rate of human body to protein.Expanding treatment also can make Partial Protein enzyme inhibition factor and the ANFs passivation in the root of kudzu vine, reduces this type of material human body is made full use of the barrier effect of beneficiating ingredient in the root of kudzu vine.Expanding treatment can also make the lipase complete deactivation in root of kudzu vine raw material, extends the shelf time of finished product.In the time that expanding treatment used is Screw Extrusion, now can select according to a conventional method general screw extruder to carry out, preferred Screw Extrusion device rotating speed is 150～200r/ minute.Advance with this understanding material can prevent excessive expanded problem.In the time that rotating speed is too low, the expanded speed of material is slower, and production efficiency is lower.
Root of kudzu vine raw material carries out ultra-fine grinding processing to it after expanding treatment, and ultra-fine grinding refers to that utilizing the method for machinery or liquid power to overcome solid interior cohesiveness makes it broken, thereby by 3 millimeters of above crushing material to 10～25 μ m.In the present invention, the first ultra-fine grinding and the second ultra-fine grinding are above-mentioned ultra-fine grinding.After the first ultra-fine grinding, the uniformity of root of kudzu vine powder, mobility, retention ability, expansive force and volume density are improved, and first ultra-fine grinding that is improved of the dissolution rate of Pueraria Flavonid also helps and retains root of kudzu vine bioactive ingredients in finished product.In the present invention the first ultra-fine grinding and the second ultra-fine grinding all routinely technique carry out, preferred the first ultra-fine grinding and the second ultra-fine grinding condition are grinding time 30 minutes, pulverize temperature-20 DEG C.By this condition processing, pulverizing speed is fast, only needs 30 minutes, and production efficiency is high.In whole crushing process, control temperature of charge and be-20 DEG C, can prevent that the root of kudzu vine active material from decomposing in crushing process, is conducive to retain bioactive ingredients in the root of kudzu vine.Ultra-fine grinding is totally-enclosed system, can effectively avoid root of kudzu vine finished product dust polluting environment.After material is expanded, after the first ultra-fine grinding, expanded starch granules particle diameter is reduced to i.e. 800～1000 orders of 15～19 μ m, and in order to ensure the effect that reconstitutes of finished product materials, after the second ultra-fine grinding, gained root of kudzu vine particle diameter is also 800～1000 orders.
The first ultra-fine grinding material after treatment is carried out to ultra high pressure treatment.Super-pressure refers to that the pressure that adopts pressure to exceed 100MPa puts on the processing means on treating material.The liquid that conventional pressure conduction medium can be water, the nonflammable viscosity of wet goods is low.Ultra high pressure treatment condition in the present invention: pressure 300～600MPa, 10～30 minutes dwell times, the water that pressure transmission medium is room temperature.Adopt this condition to process and can play bactericidal action, reduce microbe colony sum in kudzu-vine root powder.Under this condition, carry out ultra high pressure treatment to be stretched in making material and the cellulose of fracture fracture, increase soluble dietary fibre content.The amount of the long chain cellulose that affects finished product dissolution velocity is down to minimum.Under this condition, carry out ultra high pressure treatment and can make by the starch of gelatinization, gelatinization further not to be occurred in expanded step, the solution temperature of finished product is reduced.When ultra high pressure treatment pressure is lower than 300MPa, the dwell time, while being less than 10 minutes, can only kill the most of bacterium in kudzu-vine root powder, does not have the effect of sterilizing, also needs the follow-up conventional sterilization treatment of carrying out.So not only increase cost but also affected the effect that reconstitutes of finished product.When pressure is greater than 600MPa, while being greater than 30 minutes, in material, easily excessively gelatinization of starch, affected product and reconstituted effect and mouthfeel the dwell time.
Material after expanding treatment and the first ultra-fine grinding, carries out ultra high pressure treatment by this condition and can improve the breaking degree of fiber in material element and starch, thus improved finished product reconstitute effect and mouthfeel.Reconstitute temperature by this conditionity processing gained finished product and can be low to moderate 20 DEG C, and still can fully dissolve fast and reconstitute in liquid, there is no the generation of caking phenomenon.Obviously herein can not the expanded rear ultra high pressure treatment of directly carrying out, thereby larger without the expanded volume of material of fragmentation, pressurized is inhomogeneous, the effect of failing to be under pressure of most celluloses and starch.Creationary by expanded, pulverizing and super-pressure coupling in the present invention, to improve the degree of crushing of the materials such as fiber in material element and starch.Those skilled in the art it has been generally acknowledged that the starch of expanded rear material and cellulosic breaking degree have reached maximum, can not expect that residual just not starch and the cellulose of fracture cause significant impact to reconstituting with mouthfeel of finished product.And material lumps again after ultra high pressure treatment, can affect equally the effect that reconstitutes of finished product.And the present invention is on the basis of these considerations, for the treatment of the material after expanded, and adopt the method for repeatedly ultra-fine grinding to improve the effect that reconstitutes of finished product super-pressure.
